Specification of Letters Patent. Application filed November 4, 1907. Serial No. 400,566.

Patented Oct. 20, 1908.

To all whom it may concern:

cushioning pad which, while more particularly designed for the packing of fragile articles such as glass bottles, jars and the like, will be found applicable for use in other situations.

The invention consists in the various novel features of construction hereinafter de scribed, illustrated in the accompanying drawings and particularly pointed out in the claims at the end ofthis specification.

Figure 1 is a perspective'view of the pad embodying my invention, the pad being shown in flat position. Fig. 2 is a perspeclive view showing the pad bent to circular form to inclose' a bottle or like circular article. Fig. 3 is a detail sectional view of the terminal portions of the pad showing the interlockin of the ends. Fig. 4 is a detail sectional View showing a modified form of interlocking terminal flap. Fig. 5 is a detail perspective view of the end portions of the pad showing amodified means for interlocking the ends. Fig. 6 is an end view showing a modified form of pad embodying the invention. Fig. 7 is an end view of a I pad more especially designed for use as a hat pad.

Referring more particularlyito, Figs. 1

to 3 of the drawings, my improved pad there shown comprises a series of parallel cushioning members made from a sheetor strip offlexible material (preferably stout paper stock) that is bent or corrugatedto form the walls 1, 2 and 3 of the members. The walls 1 comprise the outer side and the walls 2 form the inner side of the pad, and the walls 3 which connect the walls 1 and 2 are inclined preferably at an angle of about as this will be found a most effective position for the Walls to resist crushing strain. Each of the cushionin members comprises two walls 3 connecte by the walls 1 or 2.

\Vhen the pad is intendedfor the protection of bottles, jars or like articles having curved surfaces, the cushioning. members comprising the walls or sides 1 will be slightly broader. or wider than the cushioning members comprising the walls or sides 2, the result being that the sides or walls of the cushioning members abut upon at least one side of the pad while spaces are left between the walls 2 of the cushionin members at the opposite side of the pa By this means, the pad can be bent around the circular. article to beprotected and when thus bent, as illustrated in Fig. 2, the sides or walls 2 of the narrower cushioning members will be caused to also abut or approximately abut. A retaining strip 5 of flexible material is shown as ailixed to the outer walls 101 the pad so as to hold the various cushioning members in proper relative position and this retaining strip 5 may be of any desired width, covering either partially or wholly the outer surface of the pad.

When the pad is to be used as a protective packing for a circular article, such as a bottle or the like, the ends of the pad will be brought together around such article and a will be fastened, preferably by means of one or more interlocking tongues or flaps at one end of the pad suitablyengaging with the opposite end of the pad. As shown in Fig. 1, the pad has two tongues or flaps 6 that are preferably notched or cut away as at 7 adjacent their inner ends. When the pad has been bent to circular form, the vtongues 6 will be inserted as at 8 between the abutting edges of the walls 1, 1 at each side of the retaining strip 5. The flexibility of the pad will permit'the notched portions 7 of the tongues to he slipped under the retaining strip 5 at the points 9. The terminal wall adjacent the points 9 will set beneath the corresponding terminal wall adjacent the flaps 6 when the tongues 6 have been inserted in position for use, as indicated in Fig. 2 of the drawings.

Instead of forming the flaps or ton ues 6 integral with the walls of the cushioning members, these flaps might be formed sepa-- rate and affixed to the terminal portion of th pad. So also, instead of the tongues or flaps being of the ,precise shape shown, they may be varied. Thus, in Figs. 1 and 5 the flap 6. which is shown at one end of the pad has two projecting ends and these ends will be'bent inward and inserted in. the transverse slots 11 that willbe formed in the outer wall 1 of the terminal cushioning member at the opposite end of the pad. When the pad has been bent to circulanform and the ends of the tonguefi have been forced into the slots 11, their resiliency will spread and interlock them with the wall of the pad. It is obvious that the precise construction of interlocking tongue may be varied without departing from the spirit of the invention.

In thepreferred form of the invention above described, the cushioning members of my improved pad are of triangular outline with the walls? approximately (although not ex actly) equal in width to the walls 1 and 2 and the walls 3 are at such an inclination that they will most effectively resist any crushing strains thrown upon them. Inasmuch as'the walls of the cushioning members contact upon one side at least of the pad, it follows that any ressure exerted upon suchside of the pad Wlll be distributed to the various cushioning members, thus not only giving greater resiliency to the pad but more efi'ectlvely guarding against crushing the pad at the point at which the pressure 15 applied. When the pad is bent to circular form to receive the article to be protected, the cushioning members should abut or approximately abut not merel at the outer side but also at the inner side of the pad thus increasing the strength and efliciency of the pad. And it will be readily understood that the spaces between the edges of the cushioning members upon the inner side of the pad will be greater or less according to the curvature of the articles for which the pad .is adapted.

Where my improved pad is intended for the, packing of flat articles or in situations in which any considerable bending of the pad is not required, the cushioning members may the edges of the cushioning members at thebe formed so as to abut at both their inner and outer'edges as shown in Fig. 7 of the drawing. In this form of the invention, the

.Walls 1 and 2 of the pad are of the same width. If desired, retaining strips 5 and 5* may be employed upon both sides of this form of the pad, as shown in the drawings. While in the form of the invention above described the cushioning members have a triangular shape in cross section, it is not essential that this precise shape be employed. Thus, for example, in Fig. 6 of the drawing, the pad is shown as comprising a series of cushioning members, the inner and outer walls 1' and 2 of which are curved, the connecting Walls 3 being also shown as somewhat curved. In this form of the invention outer side of the pad abut against each other, while the edges at the inner side of the pad are separated snilicientlyv to permit the pad to be bent around the curved article, such as featuresof the invention may be employed without'its adoption as an entirety.

7 Having thus described my invention what'- I claim as new and desire to secure by Letters Patent is 4 '1. A packing pad comprising a strip of stontrflexible material bent or corrugated to .form a series of cushioning members which are arranged in contact on at least one side of the pa flexible material bent or corrugated. to orm a series of cushioning members which are arranged in contact at the outer sideof the pad and are slightly spaced apart at the op-' posite side of the pad to permit said pad to be bent about the article to be protected.

3. A packing pad comprising a strip of stoutflexible material bent or corrugated to form a series of cushioning members which are arranged in contact on at least one'side of the pad, and a sheet of flexible material extending across and joining the cushioning members of'the pad.

4. A packing pad comprising a. strip of stout paper stock bent or corrugated to form a series of cushioning members which are arranged in contact on at least one side of the pad, said pad being provided at one end with a flexible flap arranged to interlock with the opposite terminal of the pad.

5. A packing pad comprising a strip of stout flexible material bent or corrugated to form a series of cushioning members which are arranged in contact on at least one side.

of the pad, one end of said pad being provided with laterally projecting tongues and the other end of said pad being provided with slots or openings to receive said tongues.

6. A packing pad comprising a continuous strip of stout paper stock bent or corrugated to form a series of parallel tubular cushioning members triangular in cross section, the outer walls of said members being broader than their inner .walls, the edges of said'cushionmg members substantially abutting at one side of the strip.
